Pluggable cloud enablement boot device and method that determines hardware resources via firmware

ABSTRACT

A pluggable cloud enablement boot device (PCEBD) is a bootable device that includes all information needed to automatically provision hardware and software to create a computing solution that meets customer requirements. This allows for quickly deploying a computing solution in a manner that eliminates many manual steps that are typically performed today. The PCEBD uses firmware to verify a given platform has sufficient resources to deploy the PCEBD. The computing solution, once provisioned and running, can be modified, and these modifications may be reflected in the definition of the PCEBD. In addition, a computing solution may include multiple resources provisioned from multiple PCEBDs, which can be packaged into a PCEBD that will include other PCEBDs. The result is a way to deploy computing solutions that is much more efficient than the manual methods used in the prior art.

BACKGROUND

1. Technical Field

This disclosure generally relates to computer systems, and morespecifically relates to deploying cloud-based computing solutions to acloud computing environment.

2. Background Art

The combination of hardware and software on a particular computer systemdefines a computing environment. Different hardware platforms anddifferent operating systems thus provide different computingenvironments. In recent years, engineers have recognized that it ispossible to provide different computing environments on the samephysical computer system by logically partitioning the computer systemresources to different computing environments known as virtual machines.The System X computer system developed by IBM is an example of acomputer system that supports logical partitioning into multiple virtualmachines. If multiple virtual machines on a System X computer system aredesired, partition manager code (referred to as a “hypervisor” in IBMterminology) is installed that allows defining different virtualmachines on the same platform. Once the partition manager is installed,virtual machines may be created that define different computingenvironments. The partition manager manages the logical partitions toassure that they can share needed resources in the computer system whilemaintaining the separate computing environments defined by the virtualmachines.

Virtual machines are used extensively in computing solutions that arecloud-based. As the demands for cloud solutions increase, open sourcesoftware for building clouds, such as OpenStack, have become a buildingblock for creating a reliable and flexible cloud platform. Withincreasing complexities and demands, cloud deployment and enablement isone of the major hurdles for cloud computing. For example, to deploy acloud infrastructure not only involves complex manipulation of physicalnodes, but also various software tools, packages and configurations.

Within a typical distributed cloud environment, there are many nodesassigned with various roles such as: Cloud Controller, NetworkController, Compute Node, and Storage Nodes. Each role requiresdifferent software packages, configurations, service end points,operating system customization, firewall rules, network settings,storage setup, security, usability, etc. Cloud enablement is currentlyhandled by field engineers who manually configure the cloud environment,and deployment time can take weeks and is very error-prone.

DETAILED DESCRIPTION

The disclosure and claims herein relate to a pluggable cloud enablementboot device (PCEBD) that is a bootable device that includes allinformation needed to automatically provision hardware and software tocreate a computing solution that meets customer requirements. Thisallows for quickly deploying a computing solution in a manner thateliminates many manual steps that are typically performed today. ThePCEBD uses firmware to verify a given platform has sufficient resourcesto deploy the PCEBD. The computing solution, once provisioned andrunning, can be modified, and these modifications may be reflected inthe definition of the PCEBD. In addition, a computing solution mayinclude multiple resources provisioned from multiple PCEBDs, which canbe packaged into a PCEBD that will include other PCEBDs. The result is away to deploy computing solutions that is much more efficient than themanual methods used in the prior art.

It is understood in advance that although this disclosure includes adetailed description on cloud computing, implementation of the teachingsrecited herein are not limited to a cloud computing environment. Rather,embodiments of the present invention are capable of being implemented inconjunction with any other type of computing environment now known orlater developed.

Cloud computing is a model of service delivery for enabling convenient,on-demand network access to a shared pool of configurable computingresources (e.g. networks, network bandwidth, servers, processing,memory, storage, applications, virtual machines, and services) that canbe rapidly provisioned and released with minimal management effort orinteraction with a provider of the service. This cloud model may includeat least five characteristics, at least three service models, and atleast four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provisioncomputing capabilities, such as server time and network storage, asneeded automatically without requiring human interaction with theservice's provider.

Broad network access: capabilities are available over a network andaccessed through standard mechanisms that promote use by heterogeneousthin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to servemultiple consumers using a multi-tenant model, with different physicaland virtual resources dynamically assigned and reassigned according todemand. There is a sense of location independence in that the consumergenerally has no control or knowledge over the exact location of theprovided resources but may be able to specify location at a higher levelof abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elasticallyprovisioned, in some cases automatically, to quickly scale out andrapidly released to quickly scale in. To the consumer, the capabilitiesavailable for provisioning often appear to be unlimited and can bepurchased in any quantity at any time.

Measured service: cloud systems automatically control and optimizeresource use by leveraging a metering capability at some level ofabstraction appropriate to the type of service (e.g., storage,processing, bandwidth, and active user accounts). Resource usage can bemonitored, controlled, and reported providing transparency for both theprovider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer isto use the provider's applications running on a cloud infrastructure.The applications are accessible from various client devices through athin client interface such as a web browser (e.g., web-based email). Theconsumer does not manage or control the underlying cloud infrastructureincluding network, servers, operating systems, storage, or evenindividual application capabilities, with the possible exception oflimited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer isto deploy onto the cloud infrastructure consumer-created or acquiredapplications created using programming languages and tools supported bythe provider. The consumer does not manage or control the underlyingcloud infrastructure including networks, servers, operating systems, orstorage, but has control over the deployed applications and possiblyapplication hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to theconsumer is to provision processing, storage, networks, and otherfundamental computing resources where the consumer is able to deploy andrun arbitrary software, which can include operating systems andapplications. The consumer does not manage or control the underlyingcloud infrastructure but has control over operating systems, storage,deployed applications, and possibly limited control of select networkingcomponents (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for anorganization. It may be managed by the organization or a third party andmay exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by severalorganizations and supports a specific community that has shared concerns(e.g., mission, security requirements, policy, and complianceconsiderations). It may be managed by the organizations or a third partyand may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the generalpublic or a large industry group and is owned by an organization sellingcloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or moreclouds (private, community, or public) that remain unique entities butare bound together by standardized or proprietary technology thatenables data and application portability (e.g., cloud bursting forloadbalancing between clouds).

A cloud computing environment is service oriented with a focus onstatelessness, low coupling, modularity, and semantic interoperability.At the heart of cloud computing is an infrastructure comprising anetwork of interconnected nodes.

Referring now to FIG. 1, a block diagram of an example of a cloudcomputing node is shown. Cloud computing node 100 is only one example ofa suitable cloud computing node and is not intended to suggest anylimitation as to the scope of use or functionality of embodiments of theinvention described herein. Regardless, cloud computing node 100 iscapable of being implemented and/or performing any of the functionalityset forth hereinabove.

In cloud computing node 100 there is a computer system/server 110, whichis operational with numerous other general purpose or special purposecomputing system environments or configurations.

Generally, program modules may includeroutines, programs, objects, components, logic, data structures, and soon that perform particular tasks or implement particular abstract datatypes. Computer system/server 110 may be practiced in distributed cloudcomputing environments where tasks are performed by remote processingdevices that are linked through a communications network. In adistributed cloud computing environment, program modules may be locatedin both local and remote computer system storage media including memorystorage devices.

As shown in FIG. 1, computer system/server 110 in cloud computing node100 is shown in the form of a general-purpose computing device. Thecomponents of computer system/server 110 may include, but are notlimited to, one or more processors or processing units 120, a systemmemory 130, and a bus 122 that couples various system componentsincluding system memory 130 to processing unit 120.

Bus 122 represents one or more of any of several types of busstructures, including a memory bus or memory controller, a peripheralbus, an accelerated graphics port, and a processor or local bus usingany of a variety of bus architectures.

Computer system/server 110 typically includes a variety of computersystem readable media. Such media may be any available media that isaccessible by computer system/server 110, and it includes both volatileand non-volatile media, removable and non-removable media. Examples ofremovable media are shown in FIG. 1 to include a Digital Video Disc(DVD) 192 and a USB drive 196, each of which may include a bootableimage 194 discussed in more detail below.

System memory 130 can include computer system readable media in the formof volatile or non-volatile memory, such as firmware 132. Firmware 132provides an interface to the hardware of computer system/server 110.System memory 130 can also include computer system readable media in theform of volatile memory, such as random access memory (RAM) 134 and/orcache memory 136. Computer system/server 110 may further include otherremovable/non-removable, volatile/non-volatile computer system storagemedia. By way of example only, storage system 140 can be provided forreading from and writing to a non-removable, non-volatile magnetic media(not shown and typically called a “hard drive”). Although not shown, amagnetic disk drive for reading from and writing to a removable,non-volatile magnetic disk (e.g., a “floppy disk”), and an optical diskdrive for reading from or writing to a removable, non-volatile opticaldisk such as a CD-ROM, DVD-ROM or other optical media can be provided.In such instances, each can be connected to bus 122 by one or more datamedia interfaces. As will be further depicted and described below,memory 130 may include at least one program product having a set (e.g.,at least one) of program modules that are configured to carry out thefunctions described in more detail below.

Program/utility 150, having a set (at least one) of program modules 152,may be stored in memory 130 by way of example, and not limitation, aswell as an operating system, one or more application programs, otherprogram modules, and program data. Each of the operating system, one ormore application programs, other program modules, and program data orsome combination thereof, may include an implementation of a networkingenvironment. Program modules 152 generally carry out the functionsand/or methodologies of embodiments of the invention as describedherein.

Computer system/server 110 may also communicate with one or moreexternal devices 190 such as a keyboard, a pointing device, a display180, a disk drive, etc.; one or more devices that enable a user tointeract with computer system/server 110; and/or any devices (e.g.,network card, modem, etc.) that enable computer system/server 110 tocommunicate with one or more other computing devices. One suitableexample of an external device 190 is a DVD drive, which can receive andread the bootable image 194 from a DVD 192 as shown in FIG. 1. Suchcommunication can occur via Input/Output (I/O) interfaces 170. Stillyet, computer system/server 110 can communicate with one or morenetworks such as a local area network (LAN), a general wide area network(WAN), and/or a public network (e.g., the Internet) via network adapter160. As depicted, network adapter 160 communicates with the othercomponents of computer system/server 110 via bus 122. It should beunderstood that although not shown, other hardware and/or softwarecomponents could be used in conjunction with computer system/server 110.Examples, include, but are not limited to: microcode, device drivers,redundant processing units, external disk drive arrays, Redundant Arrayof Independent Disk (RAID) systems, tape drives, data archival storagesystems, etc.

Referring now to FIG. 2, illustrative cloud computing environment 200 isdepicted. As shown, cloud computing environment 200 comprises one ormore cloud computing nodes 100 with which local computing devices usedby cloud consumers, such as, for example, personal digital assistant(PDA) or cellular telephone 210A, desktop computer 210B, laptop computer210C, and/or automobile computer system 210N may communicate. Nodes 100may communicate with one another. They may be grouped (not shown)physically or virtually, in one or more networks, such as Private,Community, Public, or Hybrid clouds as described hereinabove, or acombination thereof. This allows cloud computing environment 200 tooffer infrastructure, platforms and/or software as services for which acloud consumer does not need to maintain resources on a local computingdevice. It is understood that the types of computing devices 210A-Nshown in FIG. 2 are intended to be illustrative only and that computingnodes 100 and cloud computing environment 200 can communicate with anytype of computerized device over any type of network and/or networkaddressable connection (e.g., using a web browser).

FIG. 4 shows one suitable example of the bootable image 194 shown inFIG. 1. The bootable image 194 includes boot code 410, customerrequirements 420, a system verification and integration mechanism 430, abuilding and integration mechanism 440, and one or more virtual machineimages 450 that each include one or more applications 460, applicationlogic 470 and business logic 480. The boot code 410 is code that allowsan apparatus such as computer system/server 110 in FIG. 1 to initialize.Customer requirements 420 include specifications for a desired computingsolution. System verification and integration mechanism 430 verifies thesystem includes sufficient hardware resources to implement the desiredcomputing solution. The building and integration mechanism 440 uses thecustomer requirements 420 and the system resources determined by thesystem verification and integration mechanism 430 to determineinfrastructure on which the computing solution can be provisioned ordeployed, and provisions or deploys the computing solution automaticallywithout intervention of a human user to provide the computing solution.One example of the computing solution is shown at 350 in FIG. 3. Whilethe specific example of the bootable image 194 shown in FIG. 4 includesone or more virtual machine images 450, the applications 460,application logic 470, and business logic 480 can exist within thebootable image 194 separate from any virtual machine image, which willallow determining dynamically a suitable number of virtual machines todeploy based on the customer requirements, as discussed below withreference to FIGS. 15-17. The application(s) 460, application logic 470,and business logic 480 are part of the customer requirements 420 thatdefine how a computing solution is built and deployed.

The most preferred environment for implementing the computing solutionis within one or more clouds. As a result, the customer requirements 420may specify cloud resources, and the building and integration mechanism440 may build any needed cloud infrastructure, then deploy the computingsolution on the cloud infrastructure.

Applications 460 may include any suitable software applications,including cloud applications. Application logic 470 is logic needed toconfigure and run the application(s) 460. Business logic 480 includesintelligence for making the computing solution function to perform adesired task, such as a task a business needs. The combination of theapplication logic 470 and the business logic 480 provides most of thecustomization within the virtual machine image(s) 450. Thus, byspecifying applications 460, application logic 470, and business logic480, the building and integration mechanism 440 has sufficientinformation to automatically provision the computing solution withoutintervention by a human user.

Details of one suitable example of the system verification andintegration mechanism 430 in FIG. 4 is shown in FIG. 5. The systemverification and integration mechanism 430 may include a firmware/BIOSmechanism 510 that communicates with the firmware or BIOS (such asfirmware 132 in FIG. 1) to determine the hardware resources available onthe computer system/server 110. The firmware/BIOS mechanism 510 couldcommunicate with the firmware 132 in FIG. 1 via a Unified ExtensibleFirmware Interface (UEFI). The firmware/BIOS mechanism 510 includes aprocessor/memory mechanism 520, a physical disk mechanism 530, a bootorder 540, and a network for remote hardware control 550. Theprocessor/memory mechanism 520 determines the processor and memoryresources on the computer system. The physical disk mechanism 530creates a disk partition and installs a file system in the diskpartition. The physical disk mechanism 530 can extend the disk, setup ashared file system for different kinds of VM operation requirements,such as migration, fail-over, etc. Different kinds of storage, likesolid state drives (SSDs), can also be used. The physical disk mechanism530 also substitute cloud infrastructure, including a private cloud, apublic cloud, or a hybrid of private and public clouds, for the filesystem in the disk partition. The boot order specifies the order of bootdevices. Thus, the boot order 540 could specify to boot first from a DVDdrive, then boot from a USB device, then boot from the local hard disk.Such a boot order will allow a computer system to boot from a PCEBD. Thenetwork for remote hardware control 550 is a network such as anIntelligent Platform Management Interface (IPMI) network that allowsremotely controlling the hardware. The IPMI network can be used forremote provisioning, to monitor hardware status, to remove powercontrol, etc.

Examples of categories of customer requirements are shown at 420 in FIG.6 to include hardware requirements 610, software requirements 620,networking requirements 630, security requirements 640, and otherrequirements 650. Hardware requirements 610 may include the requiredplatform type and the required number of processors and memory. Softwarerequirements 620 may include an operating system, software environments,and dependencies for software packages. Networking requirements 630 mayinclude number, type and configuration of physical and virtual networks.Security requirements 640 may include any needed requirements related tosecurity, including access control lists. Other requirements 650 mayinclude any suitable requirement not specifically described in the otherrequirements 610, 620, 630 and 640 above. For example, otherrequirements 650 could specify a particular number of VMs to deploy,along with their associated application(s), application logic, andbusiness logic.

Referring to FIG. 7, a method 700 shows steps for automaticallyprovisioning a computing solution using a PCEBD. A computer system isbooted from the PCEBD bootable image (step 710). Compatibility of thecustomer requirements with the hardware is verified via the BIOS (step720). A disk partition is created (step 730). A file system is setup inthe disk partition (step 740). Required infrastructure is then built(step 750). One or more VM images are provisioned to the infrastructure(step 760). The VMs are run (step 770). At this point the computingsolution has been provisioned and is running. Method 700 is then done.

Referring to FIG. 8, a method 800 shows one suitable implementation forstep 720 in FIG. 7. The firmware is used to verify memory and processorrequirements specified in the customer requirements (step 810). When therequirements are met (step 820=YES), deployment continues (step 830).When the requirements are not met (step 820=NO), deployment is halted(step 840). Method 800 thus verifies via system firmware the computersystem has sufficient resources for deploying the computing solutionbefore deploying the computing solution.

FIG. 9 shows a disk partition that has been specifically designed forextracting the pre-built file system image from an existing virtualmachine in the lab after testing. This file system will then be used onthe customer site and re-built based on the exact file system, withoutany hardware dependency. An entry 910 in the bootable image includes aboot portion, a file system table fstable, a source partition, and adestination partition. The file system can then be created as shown inthe file system tree in a manner that is not dependent on any particulardisk type or file system.

Referring to FIG. 10, a method 1000 shows how a bootable image for aPCEBD can be defined, deployed, then modified, which can, in turn,change the PCEBD image. Thus, a PCEBD image is defined in step 1010. ThePCEBD image is deployed in step 1020, which creates a running computingsolution 1030. The computing solution 1030 may be modified, whichresults in the modifications being fed back into the PCEBD definition1010. In this manner a PCEBD at 1010 can be used to deploy a computingsolution on a test platform at 1020, the computing solution can then bemodified at 1030, and the modifications can be reflected in the PCEBDimage at 1010.

Modification of the computing solution at 1030 can be done by anysuitable person or software. One specific scenario is shown in FIG. 10,where multiple PCEBD images 1020, 1040 and 1050 are deployed to modifythe same computing solution 1030. Modifications may be done during a“test and change” phase of developing the computing solution. Theresulting modifications to the PCEBD image 1010 could include all themodifications effected by all of the deployed PCEBD images 1020, 1040and 1050. In this simple example, a first PCEBD is deployed at 1020,which results in a computing solution running at 1030. A second PCEBD isdeployed at 1040, and a third at 1050, both of which make modificationsto the computing solution 1030. The resulting modifications are thenreflected in the PCEBD image 1010 so the resulting PCEBD image 1010after being modified reflects the computing solution after beinginstantiated and modified by the various PCEBDs 1020, 1040 and 1050.Note a computing solution can be deployed in various pieces and stages.Thus, a computing solution could be subdivided into four differentcooperating portions, with each portion being deployed via a PCEBD. Notealso that PCEBDs can be nested, where one PCEBD contains one or moreother PCEBDs.

FIG. 11 shows that application logic 470 shown in FIG. 4 may includepolicies for one or more applications 1110. Policies for applicationsmay include VM boot orders; making multiple VMs as a template (VMpatterning) so next time the VMs can be instantiated together; and otherpolicies such as VM disaster recovery, which might indicate to restart aVM or migrate the VM to another host in the event of a disaster.

Business logic 480 shown in FIG. 4 may include, for example, dataintegrity/export control 1210, multi-tenant control 1220, and networkcontrol/security 1230. The data integrity/export control 1210 defineshow different entities communicate. The multi-tenant control 1220defines account control and management, for example, for billing,resource isolation, SLA, etc. The network control/security 1230specifies how networks are controlled and the security needed to accesseach of the networks. Business logic 480 may include many other featuresnot shown in FIG. 12. Business logic 480 broadly includes anyinformation that customizes the PCEBD bootable image to provide thecomputing solution.

Referring to FIG. 13, a method 1300 monitors changes to a computingsolution (step 1310), monitors changes to the application logic and thebusiness logic (step 1320), and reflects the monitored changes in thePCEBD bootable image (step 1330). Method 1300 is a different way ofshowing the process illustrated in FIG. 10 and discussed above.

Referring to FIG. 14, a method 1400 determines resource requirementsfrom the PCEBD (step 1410), determines available resources (step 1420),and generates infrastructure according to the resource requirements andavailable resources (step 1430). The resource requirements may bespecified in the customer requirements 420 shown in FIG. 4. Theavailable resources may be determined in step 1420 by the firmware/BIOSmechanism 510 shown in FIG. 5. Method 1400 is preferably performed bythe building and integration mechanism 440 shown in FIG. 4.

FIGS. 15-17 illustrate how the building and integration mechanism 440can deploy a computing solution differently depending on availableresources. We assume the PCEBD bootable image 1500 includes threedistinct tiers as shown in FIG. 15 for a three-tier application forday-trading stocks. We assume for this example that Tier1 includesactive-standby or active-active memory cache to speed Internet access,which requires a large memory but small disk space; Tier2 is a statelessweb server in a pool, to fulfill business domain logic; and Tier3 is adatabase like SQL server or MySQL in either a cluster or a master-slaveconfiguration. For the example shown in FIG. 15, the building andintegration mechanism 440 generates three virtual machines VM1, VM2 andVM3 that correspond to each of the three respective tiers. For theexample shown in FIG. 16, the building and integration mechanism 440generates two virtual machines, a first VM1&2 that implements both Tier1 and Tier 2, and a second VM3 that implements Tier3. For the exampleshown in FIG. 17, the building and integration mechanism 440 generatesfour virtual machines, a first VM1 for Tier1, a second VM2 for Tier2,and two more VM3 and VM3′ for Tier3. These simple examples in FIGS.15-17 illustrate the building and integration mechanism 440 can generateany suitable infrastructure using any suitable number of virtualmachines, depending on the available resources.

As discussed above with respect to items 1020, 1040 and 1050 in FIG. 10,multiple PCEBDs may be provisioned to modify a running computingsolution. Referring to FIG. 18, method 1800 provisions resources for afirst PCEBD (step 1810). When there are more PCEBDs to provision (step1820=YES), method 1800 provisions resources for another PCEBD (step1830), then loops back to step 1820. This process continues until thereare no more PCEBDs to provision (step 1820=NO), at which point method1800 is done. Method 1800 is also graphically represented in a differentform in FIG. 10.

One feature of the building and integration mechanism 440 is the abilityto dynamically adjust when new resources become available. Referring toFIG. 19, a method 1900 begins when additional hardware resources becomeavailable (step 1910). The computing solution can then be modified touse the additional hardware resources (step 1920). A simple example willillustrate. Let's assume the building and integration mechanism 440initially provisions three virtual machines, one for each of the threetiers as shown in FIG. 15. Let's further assume that four additionalprocessors are added to the hardware. The building and integrationmechanism can detect these added processors, and reconfigure thecomputing solution to take advantage of the new processors. Thus, VM3could be split into VM3 and VM3′ as shown in FIG. 17, with theadditional processors used in one or both of VM3 and VM3′. In additionto dynamically adjusting, the PCEBD bootable image would also be updatedto reflect the change.

It is possible to deploy the file system for a disk partition oninfrastructure, such as cloud infrastructure. For example, referring toFIG. 20, when infrastructure exists for the file system (step 2010=YES),the infrastructure could be substituted for the file system (step 2020).In some situations, a computer system may have a pre-installed operatingsystem running on a particular server computer system, and it could beundesirable to reinstall all the software due to limitations in thesoftware license. For this case, a new cloud solution could be deployedon top of the existing system.

A simple example is now provided for the three-tier day traderapplication represented in FIGS. 15-17. A bootable image of the daytrader application 2100 is shown in FIG. 21. The day trader application2100 includes boot code 2110, customer requirements 2120, systemverification and integration mechanism 2130, building and integrationmechanism 2140, and three virtual machine images 2150, 2160 and 2170corresponding to each of the three tiers in the three-tier application.Note the building and integration mechanism 2140 may generate theinfrastructure according to a day trader application topology 2142,which can be specified in the customer requirements, or which can bedynamically determined. For this specific example, we assume the daytrader application topology 2142 specifies three virtual machines, onefor each tier, which results in the three virtual machine images 2150,2160 and 2170 shown in FIG. 21. Note that each tier includes one or morecorresponding applications and corresponding business and applicationlogic. Thus, the Tier1 VM Image 2150 includes one or more Tier1 cloudapplications 2152 and Tier1 business/application logic 2154. In similarfashion, the Tier2 VM Image 2160 includes one or more Tier2 cloudapplications 2162 and Tier2 business/application logic 2164, and theTier3 VM Image 2170 includes one or more Tier3 cloud applications 2172and Tier3 business/application logic 2174.

When the bootable image 2100 for the day trader application is used toboot a computer system, the result will be the steps shown in FIG. 7 forthis bootable image. The result will be automatic provisioning of acomputing solution without intervention of a human user. Note theprovisioning is preferably done in one or more clouds, thereby providingautomatic provisioning of a computing solution to a cloud environment.One example for the three-tier day trading application once provisionedand running is shown at 2200 in FIG. 22. Note the Tier1 VM includes 2processors and 32 GB memory, the Tier2 VM includes 2 processors and 32GB memory, and the Tier3 VM includes 8 processors and 64 GB memory. Thethree VMS communicate with each other over virtual local area networks(VLANs), such as VLAN1, VLAN2 and VLAN3 shown in FIG. 22. These threevirtual machines and three VLANs are implemented within a cloud 2210.

The claims and disclosure herein provide a pluggable cloud enablementboot device (PCEBD), which is a bootable device that includes allinformation needed to automatically provision hardware and software tocreate a computing solution that meets customer requirements.
